I would agree about the need for small (or "micro") payment system. There needs to be a way for people to transfer amounts down to even one penny without incurring fees or other issues. This would empower a whole new economic model, not only for music studios as the article talks about, but for content creators of all kinds, as well as people trying to raise money, and so on.
I don't know about you, but if it was convenient, I would often pay say a nickel or a dime to read an article on The Economist, The Wall Street Journal, or to watch a high-quality video with no ads, or to download some piece of media like a TV show or a song.
The current model of subscriptions is not working well, and requires too much commitment and various fees.
This is one area where cryptos could prove themselves useful, and I think it will be hard for credit cards and banks to ever really compete due to all the legacy issues of their systems, and other reasons.
